Bit of an update. After a further bit of researching, we came across NH-3899 <https://nhibernate.jira.com/browse/NH-3899>. While its not our error (Fixed in 4.1, we're currently using 4.1.1.4000), its the commits made to fix this error that seem to be causing our error.
There was 1 commit <https://github.com/nhibernate/nhibernate-core/commit/013b5da27301adc1fab6a95d9c164d27d1eae03d> made to update the code to its current Hibernate <https://github.com/hibernate/hibernate-orm/blob/master/hibernate-core/src/main/java/org/hibernate/mapping/Column.java> counterpart, but another commit <https://github.com/nhibernate/nhibernate-core/commit/16fafd1c086257d5c72946e863a90a3433529c7f> was made almost immediately after to prevent the alias name from becoming too long, in particular the changes made to the overloaded method 'GetAlias (Dialect.Dialect dialect, Table table)' which is being referenced in our stacktraces when this error occurs. Furthermore the changes made in this commit don't appear to be based off the original Hibernate code (and neither does the original code have these changes), so it has us questioning whether or not this is correct behaviour. Relevant lines from the raised error. System.Exception: Error trying to resolve Service 'TechCertain.Web.UI.Controllers.HomeController' or one of its autowired dependencies (see inner exception for details). ---> System.Exception: Error trying to resolve Service 'TechCertain.Domain.Interfaces.IUserRepository' or one of its autowired dependencies (see inner exception for details). ---> SimpleInjector.ActivationException: The registered delegate for type ISessionFactory threw an exception. Unique suffix 10_ length must be less than maximum 3 characters. ---> NHibernate.MappingException: Unique suffix 10_ length must be less than maximum 3 characters. at NHibernate.Mapping.Column.GetAlias (Int32 maxAliasLength) <0x41529310 + 0x00219> in <filename unknown>:0 at NHibernate.Mapping.Column.GetAlias (NHibernate.Dialect.Dialect dialect, NHibernate.Mapping.Table table) <0x41529240 + 0x0008d> in <filename unknown>:0 At this stage we're not sure how to proceed. The Stackoverflow recommended solution <https://stackoverflow.com/a/39047655> is to create a custom class and override the 'MaxAliasLength' property, but we've tried this without success (Nibernate fails to load the class). The only other option we have is build NHibernate from source without the second commit capping the alias length and ship it in place of the official distribution. If this second commit is actually enforcing correct behaviour, then we'll have to figure out why the aliases are getting so long. Any advice and/or additional insight would be welcomed.
